Evo all works fine, added Evo start lte with the rfa2a cable.

Question

The Evo all has been installed for almost a year and works fine, even after the failed Evo start lte.  I plugged the blue connectors from the rfa2a and the start wire harness. Unplugged the 4 wire data plug from the Evo all, taped off it off for protection, and plugged the 4 wire data plug from the rfa2a harness. The black and red wires are not connected and taped off.  When I go to program the start, by disconnecting the data port and holding the program button nothing happens. I used the harness for my car also when installing the Evo all. I also flashed the Evo all . Did I miss a step or something?
